BIRMINGHAM, Ala. (AP) - The Birmingham, Ala., airport has reopened after a threat prompted an investigation by bomb technicians and an evacuation of more than two hours.

Airport officials said in a Facebook post around 6:30 p.m. CDT that the airport was secured and normal operations were resuming. They said the threat was received around 4 p.m., prompting the evacuation.

FBI spokesman Paul Daymond said the agency's bomb technicians worked with local police to investigate.

Police spokesman Johnny Williams told al.com that nothing was found after bomb dogs and officers did a sweep of the airport.

The Alabama airport's website says several flights into the airport are being diverted.

Flights were delayed or diverted during the shutdown, according to the airport website. Evacuees posted pictures of dozens of people outside the airport after the threat.

Calls to authorities by The Associated Press seeking further information on the reopening weren't immediately returned.

The Birmingham airport is a small regional one with more than 100 flights a day.
